SHADOWS ARE NOT LIMITED BY LIGHTSPEED
To make black on a projector, you have to shine bright light over dim light. When the brighter light hits, the dimmer one turns black, it turns into shadow. This is gonna get deep, you're gonna need to watch this before moving on:

Now, a thought experiment. Imagine I have a really wide laser. The laser is shining a beam forward. Around the laser, I have three more lasers, infrared lasers. Despite not being able to see these lasers, when they cross they make an orb of light.
A few feet out from the beginning of the laser beam, you cross the three infrared lasers and make a point of light in the beam where they cross. This light is not as intense as the light of the beam, so now you have a point of shadow in the beam. By changing the angle of the crossed lasers, you can move the point-shadow around and through the beam without limit of the speed of light. Just a small twitch and the point-shadow moves miles.
Our universe is absolutely FILLED with light, it's absolutely everywhere. Shadows are created when an object steps in front of the beam. As we learned, a shadow is just what happens when a weaker light interacts with a brighter light. This means objects, us included, are shadows of energy. I can see you so you are obviously emitting light, if I put you in front of a brighter light, you become a sillouhette.
This is why teleportation and portals are certainly real. If you entangled two planes of space, you are just creating an interference pattern in the light between the two points. When an object goes through, it becomes a silhouette, a shadow, and the speed of light no longer applies. It moves through the light as an interference pattern, a shadow unrestricted by the speed of light.
This is why portals can work. You are going to a new place, but it's hard to say you "move". Our universe is magical, but understanding it, and unlocking its full potential, requires a better understanding of energy.
